HEATING AND VENTILATING SYSTEM.

Application filed August 24, 1925.

This invention relates to improvements in heating and ventilating systems for houses and other buildings.

It is the object of this invention to produce an indirect heating system that shall be highly efficient, cheaply installed and which will be so related to the building that it will be inconspicuous and take up little or no useful room.

It is a further object of this invention to produce a system that shall be provided with means for diluting the hot air with cold fresh air from the outside and which shall also have means for producing a forced circulation of air both with respect to the feeding of the hot air to the rooms and the return of the air from the rooms.

My invention can be best described and will be most clearly understood when reference is had to the accompanying drawing in which it has been illustrated and in which:

Fig. 1 is a plan view of one part of a building which is equipped with my system of heating;

Fig. 2 is a section taken on line 2-2, Fig. 1;

Fig. 3 is a section taken on line 3-3, Fig. 1, and

Fig. 4 is a diagrammatic representation of the thermostatic control mechanism.

In the drawing numeral 1 designates a steam boiler which may be of any desired type and capacity and has been shown merely as a diagrammatic representation of a boiler. The boiler 1 is located close to the walls of a hot room 2. This room contains a radiator 3 which is connected to the boiler 1 and is supplied with steam from the lat-- ter. An opening 4 in the outer wall connects the interior of room 2 with the atmosphere, The effective size of this opening is controlled by means of a plurality of shutters 5, one edge of each of which is connected with a bar 6 so that they can only be rotated together. A spring 7 is connected to the lower end of the bar 6 and tends to move the shutters 5 to closed posi tion. An arm 8 which is pivoted at 9 has its outer or free end connected to the bar 6 by means of a connecting rod 6 that is pivoted to the upper end of the rod 6 and to the armature at 10. An electromagnet 11 is located directly above the soft iron armature member 12 so that it will attract the Serial No. 52.210.

opening in the centrifugal fan 18 which is preferably driven by the electric motor 19. The delivery port of this fan is connected by means of a pipe 20 with the duct 21 that is located under the basement floor. From this duct branch ducts 22 extend to the .outer walls, in which they rise, and open into the rooms directly underneath the windows in the manner shown in Fig. 2. Return flues 23 extend from the inside walls of the rooms to an opening in the center of the floor of room 2.

hen the house is to be heated the radia tor 3 is heated with steam from the boiler. This makes the interior of the room 2 very hot. The fan 18 is now started and this sucks hot air from the room and forces it through the ducts into the rooms where it enters directly underneath the windows, and froinwhich the air returns to the room 2 through the return ducts 23. When the temperature in the house reaches the desired value, the thermostat 13 operates to energize the electromagnet 11 which opens the shutters 5 and lets fresh cold air into the room from the outside. As soon as the temperature falls below the desired value, the electromagnet 11 is deenergized and the shutters close, thereby excluding the fresh coldair. In this manner the temperature is automatically maintained substantially constant.

Another and obvious advantage of this construction over installations using radiators is that with my present construction the space ordinarily occupied'by the radiator is made available. v

The hot air coming up along the inside of the windows prevents these from becom ing frosted, which is a great consideration for stores located in cold climates as itv keeps the show-window clear.

Having now described invention What I claim as new is:

A heating system for houses comprisin in combination. a chamber having four side walls one of which is formed by a portion of the outside wall of the house to be heated, said outside Wall having an opening, a rediator located Within said chamber, a boiler, means for connecting the boiler With the 10 radiator, One of the side Walls 01"- said chami her having an opening near the upper end a flue having one end connected to the opening in the side wall and the other connected to a duct in the floor, an electric fan in said flue, said chamber having a return duct opening in the floor and means for varying the opening in the outside Well.

In testimony whereof I attix my signature.
